How do I configure ExpressVPN on pfSense?

To configure ExpressVPN on pfSense, one must first log into the pfSense device's web interface and navigate to the VPN section. From there, create a new VPN connection using the OpenVPN protocol. One should obtain the necessary configuration files from ExpressVPN's setup page, which includes server information and certificates. Import these files into the pfSense setup to ensure proper authentication and encryption. Next, set up a new interface for the VPN connection and configure the firewall rules to allow traffic through this interface. Finally, adjust pfSense's NAT settings to route internet traffic through the VPN tunnel. It is crucial to save all changes and restart the pfSense device for the configurations to take effect, resulting in a secure VPN connection using ExpressVPN on your network.
